Chronic hypersensitivity pneumonitis (HP) arises from repeated exposure to causative antigens. Although HP can be challenging to diagnose, it is important to differentiate from idiopathic pulmonary fibrosis and idiopathic non-specific interstitial pneumonia. HP has a unique management approach and portends a unique prognosis. The present article summarizes the recent published literature on chronic HP and highlights the features that may be helpful in distinguishing it from other chronic interstitial lung diseases.
